Fix typing errors (#39)
* Remove obsolete option `strict_boolean` It was removed back in 2018: https://github.com/python/mypy/pull/5740/files modified: tox.ini * Deactivate all mypy options This still leaves 47 errors, which should be fixed one by one. modified: tox.ini * Fix signature for `output` `client_host` is either a str or None. modified: ssh-audit.py * Fix return value for `output_recommendations` It is a bool, not None. modified: ssh-audit.py * Fix type comment for `output_fingerprints` modified: ssh-audit.py * Fix type comment for `output_security` modified: ssh-audit.py * Fix type comment for `output_security_sub` modified: ssh-audit.py * Fix type comment for `output_compatibility` modified: ssh-audit.py * Fix type comment for Socket.__init__ modified: ssh-audit.py * Simplify check for regex result ... which also fixes four typing errors. modified: ssh-audit.py * Fix typing error by simplifying regex result check modified: ssh-audit.py * Fix typing errors by simplifying regex result check modified: ssh-audit.py * Fix typing errors by simplifying regex result check modified: ssh-audit.py * Fix typing errors by simplifying regex result check modified: ssh-audit.py * Fix typing errors by simplifying regex result check modified: ssh-audit.py * Fix typing errors by simplifying regex result check modified: ssh-audit.py * Fix typing error by simplifying regex result check modified: ssh-audit.py * Fix typing error by simplifying regex result check modified: ssh-audit.py * Fix typing error by simplifying regex result check modified: ssh-audit.py * Fix typing error by simplifying regex result check modified: ssh-audit.py * Fix typing errors by simplifying regex result check modified: ssh-audit.py * Fix typing errors by simplifying regex result check modified: ssh-audit.py * Fix typing error by simplifying regex result check modified: ssh-audit.py * Fix typing error by simplifying regex result check modified: ssh-audit.py * Fix typing error by simplifying regex result check modified: ssh-audit.py * Fix typing error by simplifying regex result check modified: ssh-audit.py * Fix type comment for OutputBuffer.flush modified: ssh-audit.py * Fix type comments for `output_algorithms` modified: ssh-audit.py * Fix type comment for `output_algorithm` modified: ssh-audit.py * Fix type comment for KexGroup14's init method modified: ssh-audit.py * Fix type comment for KexDH's send_init modified: ssh-audit.py * Fix type comment for KexDH's init method modified: ssh-audit.py * Add explicit return value of None Now this is odd. Python has an implicit return value of None for `return`, but mypy does not infer that. modified: ssh-audit.py * Fix type error for unknown_algorithms modified: ssh-audit.py * Add type comment for Socket.__sock_map modified: ssh-audit.py * Create type comment for Kex.__host_keys modified: ssh-audit.py * Create type comment for Kex.__dh_modulus_sizes modified: ssh-audit.py * Add type comment for Kex.__rsa_key_sizes modified: ssh-audit.py * Fix type eror by adding type comment to temp variable modified: ssh-audit.py * Fix type comments for Auditconf.__setattr__ modified: ssh-audit.py * Fix type error by simplifying branch logic modified: ssh-audit.py * Do not skip type checks any more Without additional strict options, there are zero type errors (down from 47). modified: tox.ini * Annotate variables before tuple unpacking modified: ssh-audit.py * Annotate variables before unpacking modified: ssh-audit.py * Fix flake8 issues modified: ssh-audit.py
